`.rpplcation filed April 9, l9'8. Serial No. @7502.

Ec. it known that l, l'laLrn G. 'Wnri'LoriL a citizen ot the linited States. residing' at. the city ot Los Angeles, State ot alit'ornia. have invented new and usetul improvements in Lowe-Leal Books. ot which the tollowinn' is a specilieation.

My invention relates Vtothe construction of the metal portions ot the cover or case. which. tor distinction. l call theI bach trame. and the object thercoll is" to eheapen the construction ot such portions and to provide simple means tor opening' and closing' the ring members which. at the same time. locks .them in't'heir closed or holds them in their open positions.

A `further object is to provide a simple member which is hound in the cove and which co-acts with the lea't holding,` member and quickly and easily secures the same to the cover.

ln the drawings forming' a part ot this appl' jation:

Figure l is a plan looking' at the rings.

Fig. "Z'is au enlarged view ot the lock end.

Pig. 3 is a plan ot the sheet metal blank which forms a part` oit the lea't holding member iat'ore the same. E'ormed tor use.

Fig. l is a plan ot the leat' holdingY member ,of Fig'. l looking' at the same from the reverse side. with the locking' lever' in open position.

Fig. 5 is a. plan view ot the cover member.

Fig. t' is an edge view ot thicover rieurber partly broken away.

Referring to the drawings: l0 is a strip ot sheet metal which i5 Ytermed with turned over ends l1 and 12 and which has lugsl?) struck up near the upturued ends as best shown in Figs. 5 and ll. and forms what l term the cover member oi the back trame. This cover member is bound up with the material ot which the cover is made and lies between the lining' and outer surface of thatl portion ot' the cover which forms the back. The upturned ends il and l2 and ends ot lugs 13 project. through the lining` after the lcame is positioned. The lea]u holding' member is composed of a body plate 1l whose edges are partly eut away and the uncut portions are turned over to form on one side bearings l5 in which are mounted the stationary ring' members 1G, and on the other side bearings 1T in which are rotatably mounted the movable ring: members i8. The .stationary ring members are pre 'ably formed ot heavy wire which is bent at the ends into halt' rings winch pro]ect over the plaie. .Below the plate these members have an oli'set portion 19 across which bearings l5 pass thereby holding the oti'set portions in contact with the pla-te and. the members rigid or stationary7 with reference to the plate. The movable ring' members 1S are lpreferably 'formed ot' heavy wire which is bent. at the ends into halt ring members which project above theI plate. Below the plate one ot' these members has a slight bend as shown at Q0 in Fic'. 4. which forms 'whatA l term a friction and stop lug as ity bears against plate il when the rings are being opened-and contacts with the downturned edge ot the plate when the rings are tally opened and stops their further movement. ln the drawings l have shown a tour ringl device but` the same nifty" be constructed to have only two rings. l'n a four ring` devicel it will. be observed that the half ringmembers are'y constructed in pairs and that the pairs oi movahlehalf ring` meinbers are connected by a short tube '21 to which the are soldered or otherwise rigidly united. An opening' arid closing` L-shapedrlever is connected to one oft the pairs of the movable hall ring members by n mns ot' a short. tube 23 into which the, sfhanl .ot lever passes and which is rigidly! united thereto and to the half ring" lmember by solder or otherwise. The shank ot lever '22 passes through a bearing 24 formed out .of the edge of plate ll. 'To the end of lever 2'2 is pivotally7 connetted the locking plate Q5 which is adapted to be swung' open as shown in Fig.' -l when the ring` members are to be opened, or to be swung shut when the ring members are in their closed position as shown in Fig. .l and thereby lock them in such position. As plate is swung to its locking' position the curved edge thereof passes into an aperture 2G in the end ot plate 14. For ease in opening pro'iiide an aperture 27 in plate In the ends i t the blank out of which plate 1l is formed lare notches 28 in which are received the up-l turned lugs 13 of the cover member..

As shown in Fie. 3 there is an outer dotted line across each ot the ends ot the blank at the rear ol' notches 28 and inner dotted lines near the first lines.

The ends et the blank wartlly and at rigriit angles to vgitlidi- 'nal plane at. the inner dotted lines anti bent are bent. downoutwardly on the outer lines, so that the sides of notches 28 lie in a plane parallel with the plane of the plate.

As before stated the cover member is bound up With the material out of Which the cover is formed and the lugs 13 thereof project inwardly above the lining. The ring members having been assembled as hereinbefore described are positioned by sliding one end thereof under the turned end 11 of the cover member and then pushing the other end down into contact thereof. In so doing notches 28 straddle lugs 13. One of the upturned ends 12 of the cover member when it is bound in the cover is left atan angle as shown in Fig. 6 to permit this moyement of the ring member and after the ring member Vis thus positioned, end 12 is bent down and holds that endfromrising and coming 0ut. By this construction it-vvill 'be seen that the cover containing the cover member is manufactured as a separate unit from the ring member'which is afterward connected thereto` by means of co-acting parts which cfu' be quickly and easily positioned. A It will alsovbe'observed that the ring member is adapted to hold leaves and form aloose-leaf boo Witnout the cover.

Having described my invention, I claim 1. In a loose leaf book a cover member having upturned overhanging ends and lugs struck therefrom projecting toward the over` hanging ends, said member being adapted to be bound inthe cover with the lugs and overlapping ends projecting Vabove the lin` lng.

`v2. In a loose leaf |book a ring` member comprising a body plate having portions of the edges turned to form 'bearings and the ends notched and turned downwardly and` the portions forming the sides of the notches turned outwardly, one of said ends having an aperture therein; half ring members mounted in said bearings, the half ring members on one side being movablel and *those on the other side being stationary with reference Ato the bodyl plate; and means connected to the movable members to move the same and to lock the same in their closed position, said locking means entering said aperture.

3. In a loose leaf book a cover member be bound in the cover With the lugs and overlapping ends projecting above the lin.`

ing, in combination With a ring member comprising a body plate having notches. in the endsthereof adapted to straddle the lugs of the cover-member and to be connected thereto when the overlapping ends of the cover member are positioned, said body plate having `portions`of the edges turned to form bearings; half ring members mounted in said bearings, the half ring members on one side being movable and those on the other side being stationary with reference to the body plate; and means connected to the movable members to move the same and "t/o lock the same in their closed position.

Ll. In a loose leaf book a ring member comprising a body plate having portions of the edges thereof turned to form bearings and turned ends, one of said ends having an apv erture therein; half ring members rigidly mounted in said bearings on one side of said plate; co-acting half ring members mounted for oscillating movement 'in the bearings on the other side of said plate; an L-shaped lever connected to the movable half ring members; and a locking plate pivot-ally con` nected to said lever and adapted to be swung so that a portion thereof Will enter the vaperture in the turned end of said plate when the ring members are closed, and thereby lock the same from opening.

5. Ina loose leaf Ibook a ring plate having portions of the edges thereof turned to form bearings; a plurality of pairs of half ring members movably'mounted in the bearings on one side,v and a plurality of coacting ring members mounted in the bearings on the other side, said last members to be stationary With reference to said plate; means to connect the pairs of movable half ring members; means to move said movable members; and n'ie'ans to locl said movable members in their closed position.

In witness that I claim the foregoing I have hereunto subscribed my name this 4th day of April 1918.
